lnvention 1s the providing in connection with the visibility as tocontents means for protection from surreptitiously rem oving thecontents.

\Vith the foregoing and other objects in View, my invention consists ofthe novel construction, combination and arrangement of parts ashereinafter specifically described and illustrated in the accompanyingdrawing, wherein is shown the preferred embodiment of my invent ion,-butit is understood that changes, variations and modifications can beresorted to .which come within the scope of the 'claimhereunto appended.

While my invention relates primarily to a food vending machine,

for containing pies and sandwiches and other perishables of thatcharacter, I do not wish to be limited to those articles.

I am aware that there area great many vending machines similar inappearance to the one herein-described, many much more complicated andbut few, if any,

more expensive to construct, that have so few parts and none of suchsimplicity ofconstruction with the p protection after 16d my design.

especially adapted In the drawings of the herein-described embodiment ofmy-invention, Fig. 1 is aperspective in use. Fig. 2 is a face view theinterior parts of the machine broken off and removed from the case.Figs. 3 and 4. are the two side views in elevation respectively of theinterior of the machine removed from the case broken off, asshown inFig. 2; Fig. 5 is a sectional-view taken through 5-5 of Fig. 4'; Fig. 6is an enlarged sectionalview in elevation of the bottom of the casingand lower front; Fig. 7 is an enlarged perspective view of the undersizecoin-detector; Fig. 8 is a plan View of the undersize coin-detectorshown in Fig. 7 Fig.9 is a sectional view of the undersize coin-detectortaken through 9-9 of Fig. 7

Fig. 10 is a view taken through 10-10 of Fig. 7, and shows the third;coin-detecting means; Fig. 11 is an enlarged view of the coin shieldtaken in elevation; Fig. 12 is an end view in elevation of the coinshield shown in Fig. 11, and'Figf13 is a. plan view of the coin shieldshown in Fig. 11.

Similar numerals refer to similar parts throughout the several views.

1 is the main outside casing; it is provided with upper front 2 andlower, front 8. t is the top cover which'is hinged on the back of thecasing 1 and is provided with means for folding down on the topof casing1, being locked to upper front 2 when in position by lock 6, thelowerend of upper front locked in front of lower. front 3 by lock 7 at itsupper end, the lower part of lower front 3 being caught under outsidecasing 1 in a hinged fold at 5.

The arrangement of the upper and lower fronts are such that the operatorin filling the machine need not unlock lock 7, thus maintaining themechanism and coin box out of his. reach.

Within casing 1 is placed the operating part of the vending machinewhich consists of'magazine 8 and table 9 provided with supportingflanges 10 upon which rests the goods 11, to be sold. Undersupporting'flanges 10 operates slide 12 provided with hook projections13, the object of the-hook being to form a finish on the top of theprojection of such a character as to permit of its retrieving movementunder the weight of the goods above the same, without injury to thepackage.

View of the machine assembled as 1n elevation of,

2 being coin shield drops from coin. shield 30 Slide 12 is provided withdraw-bar 14;, at the end of which-is a ring 15, or other suitable orconvenient means to grasp with the fingers. This draw-bar 14: operatesthrough lower front 3, the front being slotted as shown to permit ring lto go through the same, said draw-bar being I front end of the table byguide 16. Slide 12 is provided with retrieving means, shown as a spring17, in the drawings.

18 is a hook, or coin-operated locking means, for slide 12, and isfulcrumed to the coin shield at 19 and engages over projection. 20 underthe slide 12, thus preventing the slide from operating when in.retrieved'position'. To raise hook 18 in order to release projection 20a coin, 21, of the correct dimension is necessary. A coin is introducedthrough the upper front 2 at coin slot 22, which slot is substantiallythe size of the proper coin, thus acting as a first check on the coinfor over-size. The coin in its pregress goes down chute 23, in whichchute'on the upper edge is an undersized coin eliminator consisting of ameans 2 1 for tilting the coinout of the vertical to a limited extent,causing the same to bear against top chute guide 25, if of proper size;if under-size, however, it will miss top chute guide and fall over intothe outsi le casing and not follow the chute to the releasing mechanism,thus forming the second protective device.

The coin of the proper size in its progress comes to elbow in the chute,at which point is magnet 27, the chute at about this point being cutaway to permit a slug of magnetic metal to be attracted from its line ofprogress in the chute to opening 28 where it is eliminated from thechute and dropped into the outer casing, this forming the thirdprotective device.

The coin, dropping through the lower or vertical section of 29 of thechute, enters the 30. Hook 18 is fulcruined to this shield, said shieldbeing secured to the table 9. The coin engages hook 18 at or near itsfulcrum.

In coin shield 30 operates coin push projection 38, which projection issecured to slide 12 operating through. slot in the table and behind thecoin, so that upon pulling slide 12 bymeans of ring 15, push projection38 carries the coin with the slide and in doing the coin lifts the hookaround its fulcrum tosuch an extent that it disengages hook projection20 under the slide, there being sufficient back-lash to permit of thismovement. The slide being free may be pulled to the limit of its action,and in doing so it pulls the bottom package of goods 11 with it by meansof book projection 13; The coin, near the limitof' the slide withdrawal,into the coin receptacle 3-1.

Coin receptacle 31 consists of a funnel steadied at the,

in bands, then drawing box hinged at its lower end at 32 so that it maybe easily tilted to discharge its contents and be replaced in positionagain and is formed out of a single piece, as shown.

Specially referring to the coin shield, 30,

hook 18 fulcruined thereto and being pro vided with coin guide a, lowerrunway of the chute Z2, definitely spaced with reference to the fulcrumend of the hook so that it requires an exact size coin to lift the hooksufficient to disengage the slide; it is also provided with spacing andaligning members 0. In fact, by one operation it is formed ready forassembly. 1 j

The slide being pulled out with the lowerpackage of goods, upon reachingthe ends of supporting flanges 10 the goods fall off into delivery chute33, where they can be reached by the purchaser.

Hook projections 13 are fulcrumed to the slide so that they are normallyheld in po sition, as shown in Fig. 2; that'is, in en'- gaging position,a spring or: other dcsir' able means 7 operation they operate wheninthis position until the delivery of the lower package of goods; whenthe package over the same drops on top of these projections they yieldto the same and slide under the lower package during the. retrievingmove ment of the slide until th y are behind the lower package and freeto regain their nor-v mal position.

41 is a slot closer to automatically prevent the introduction of a coinwhen the machine is empty, and is fulcrume'd at 35, forming a bell-crankthe other end of which is secured by means of a link 36 to hell-- crank37, the other end of bell-crank 3? be ing a pedal,- or projection, underthe goods in the magazine and held down by thesa'me; when 1' saybell-crank 37', I mean a shaft provided with a pedal on one end and atthe other end a crank so that the-j-pedal' may be in the rear of themachine when the lever is at the front of the niacl'iin'e, thus formingin substance a-bell-crank operation; the shutter operates directlybehind coin-slot inupper front in front of chute 23, the weight of'link- 36 being suf licieut to close the slot closer when there are nogoods on the pedals.

The operation of my invention is as follows: s

Themaehine being assembled as shown in Fig. 1, the magazines are-filledby opening top cover 4 and int'roducing'the' package's out the handsThis, however, is not necessary,- but is simple way of filling. The?coin removed by flak ing off both fronts and tipping the" money beingused for this purpose. In 7 box, as previously suggested. The slugs arescraped out of the bottom of the casing and are not found in the moneybox. v

Having thus described my invention, What 5 I claim and desire tosecureby Letters Patent is:

In an organized Vending machine provided With a coin controllingapparatus, a

coin shield consisting of stamped sheet metal 10 provided with a lowerrunway, a guide at said fulcrum being such that a proper sized coinienteringsaid guide operates said hook to lift the same when pushedalong said runway by said slide.
